Title: Aromatic deodorizing formation
Inventor: ITO KENZO
IPC: A61L9/01
Filed: 1994-03-04
Abstract: PURPOSE:To provide an aromatic deodorizing formation excellent in the durability of fragrance by conducting combination by bringing perfume into contact wrappingly with cyclodextrin and/or cyclodextrin derivative. CONSTITUTION:An aromatic deodorizing formation is obtained by containing perfume and cyclodextrin and/or cyclodextrin derivative. In this instance, any of alpha type, beta type, gamma type cyclodextrin can be used, and when economy is considered, the beta type cyclodextrin is preferable. As the soluble degree of betacyclodextrin is low with 1.8g/100g water, the freedom degree of disposition is narrow and its stability is uncertain, and therefore cyclodextrin derivative is desirable when stability, economy and the freedom degree of disposition or the like are considered. Hydroxypropyl-beta-cyclodextrin is most preferable as cyclodextrin derivative. The durability of the fragrance of the aromatic deodorizing formation is improved by regulating the combination amount of water, alcohol, a humidifying agent and an organic solvent and making it into a gel state.
